Aim of investigation: The aim of this investigation is to find out how the concentration of the starch (substrate) affects the activity of amylase (the enzyme) Prediction I predict that as I increase the substrate concentration the activity of the enzymes will increase until a point where the rate of reaction will stay constant. My predicted graph will look like this The enzyme, busily going about its catalytic work, will simply hang around until a substrate molecule collides with it appropriately. In the same way that increasing the temperature increases the chances of a favourable collision, so increasing the substrate concentration increases the chances - because there are simply more substrate molecules kicking about! However, there's only so much work that each enzyme molecule can do. Eventually you'll reach a stage where there are more substrate molecules than there are enzyme molecules to work their magic - so, as the image hopefully shows,...
